     in which R 1 , R 2 , R 3 , R 4 , R 5 , R 6  and Z are as defined in the disclosure, and to the preparation of such intermediates.

The present invention relates to novel iodopyrazolylcarboxanilides, to a plurality of processes for their preparation and to their use for controlling unwanted microorganisms.

It is already known that numerous carboxanilides have fungicidal properties (cf., for example, WO 93/11117, EP-A 0 589 301, EP-A 0 545 099, JP-A 2001-302605, JP-A 10-251240 and JP-A 8-176112). Thus, N-(2-cyclopentylphenyl)-3-iodo-1-methyl-1H-pyrazole-4-carboxamide, N-(2-cyclohexylphenyl)-3-iodo-1-methyl-1H-pyrazole-4-carboxamide, N-(2-cycloheptylphenyl)-3-iodo-1-methyl-1H-pyrazole-4-carboxamide, N-(2-cyclooctylphenyl)-3-iodo-1-methyl-1H-pyrazole-4-carboxamide and N-(2-bicyclo[2.2.1]hept-2-ylphenyl)-3-iodo-1-methyl-1H-pyrazole-4-carboxamide are already known from WO 93/11117, N-(4′-chloro-1,1′-biphenyl-2-yl)-1,3-dimethyl-1H-pyrazole-4-carboxamide is already known from EP-A 0 589 301 and N-[2-(1,3-dimethylbutyl)phenyl]-1,3-dimethyl-1H-pyrazole-4-carboxamide is already known from JP-A 10-251240. The activity of these compounds is good; however, in some cases, for example at low application rates, it is unsatisfactory.

Surprisingly, the iodopyrazolylcarboxanilides of the formula (I) according to the invention have considerably better fungicidal activity than the constitutionally most similar active compounds of the prior art having the same direction of action.

If appropriate, the compounds according to the invention can be present as mixtures of different possible isomeric forms, and in particular of stereoisomers, such as, for example, E and Z, threo and erythro and also optical isomers, and, if appropriate, also of tautomers. What is claimed are both the E and the Z isomers, and the threo and erythro and also the optical isomers, any mixtures of these isomers, and the possible tautomeric forms.

If appropriate, they can also be used as intermediates and precursors for the synthesis of further active compounds.

All plants and plant parts can be treated in accordance with the invention. Plants are to be understood as meaning in the present context all plants and plant populations such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional plant breeding and optimization methods or by biotechnological and recombinant methods or by combinations of these methods, including the transgenic plants and inclusive of the plant cultivars protectable or not protectable by plant breeders' rights. Plant parts are to be understood as meaning all parts and organs of plants above and below the ground, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruit bodies, fruits, seeds, roots, tubers and rhizomes. The plant parts also include harvested material, and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, offshoots and seeds.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquefied gases under pressure, and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants, and/or foam formers. If the extender used is water, it is also possible to employ, for example, organic solvents as auxiliary solvents.

Liquefied gaseous extenders or carriers are to be understood as meaning liquids which are gaseous at standard temperature and under atmospheric pressure, for example aerosol propellants such as halogenated hydrocarbons, or else butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals such as finely divided silica, alumina and silicates. Suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, corn cobs and tobacco stalks. Suitable emulsifiers and/or foam formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulfonates, alkyl sulfates, arylsulfonates, or else protein hydrolyzates. Suitable dispersants are: for example lignosulfite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other possible additives are mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally comprise between 0.1 and 95 percent by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention can be used as such or in their formulations, also in a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, to broaden, for example, the activity spectrum or to prevent development of resistance.

WO-96/37494, WO-98/25923), and also preparations which comprise insecticidally active plant extracts, nematodes, fungi or viruses.

A mixture with other known active compounds, such as herbicides, or with fertilizers and growth regulators, safeners or semiochemicals, is also possible.

In addition, the compounds of the formula (I) according to the invention also have very good antimycotic activity. They have a very broad antimycotic activity spectrum in particular against dermatophytes and yeasts, molds and diphasic fungi (for example against Candida species, such as Candida albicans, Candida glabrata), and Epidermophyton floccosum, Aspergillus species, such as Aspergillus niger and Aspergillus fumigatus, Trichophyton species, such as Trichophyton mentagrophytes, Microsporon species such as Microsporon canis and audouinii. The list of these fungi by no means limits the mycotic spectrum covered, but is only for illustration.

The active compounds can be used as such, in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. Application is carried out in a customary manner, for example by watering, spraying, atomizing, broadcasting, dusting, foaming, spreading, etc. It is furthermore possible to apply the active compounds by the ultra-low-volume method, or to inject the active compound preparation or the active compound itself into the soil. It is also possible to treat the seeds of the plants.

When using the active compounds according to the invention as fungicides, the application rates can be varied within a relatively wide range, depending on the kind of application. For the treatment of parts of plants, the active compound application rates are generally between 0.1 and 10 000 g/ha, preferably between 10 and 1000 g/ha. For seed dressing, the active compound application rates are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. For the treatment of the soil, the active compound application rates are generally between 0.1 and 10 000 g/ha, preferably between 1 and 5000 g/ha.

As already mentioned above, it is possible to treat all plants or their parts in accordance with the invention. In a preferred embodiment, wild plant species or plant varieties and plant cultivars which have been obtained by traditional biological breeding methods, such as hybridization or protoplast fusion, and the parts of these varieties and cultivars are treated. In a further preferred embodiment, transgenic plants and plant cultivars which have been obtained by recombinant methods, if appropriate in combination with conventional methods (genetically modified organisms), and their parts are treated. The term “parts” or “parts of plants” or “plant parts” has been explained above.

Plants which are treated particularly preferably in accordance with the invention are those of the plant cultivars which are in each case commercially available or in use. Plant cultivars are understood as meaning plants with new traits which have been bred either by conventional breeding, by mutagenesis or by recombinant DNA techniques. They may take the form of cultivars, breeds, biotypes and genotypes.

Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, nutrition), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, reduced application rates and/or a widened activity spectrum and/or an increase in the activity of the substances and compositions which can be used in accordance with the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to salinity in the water or soil, increased flowering performance, facilitated harvesting, accelerated maturation, higher yields, higher quality and/or better nutritional value of the harvested products, better storage characteristics and/or processability of the harvested products are possible which exceed the effects which were actually to be expected.

The preferred transgenic plants or plant cultivars (those obtained by recombinant methods) to be treated in accordance with the invention include all those plants which, owing to the process of recombinant modification, were given genetic material which confers particular, advantageous, valuable traits to these plants. Examples of such properties are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to salinity in the water or soil, increased flowering performance, facilitated harvesting, accelerated maturation, higher yields, higher quality and/or higher nutritional value of the harvested products, better storage characteristics and/or better processability of the harvested products. Further examples of such traits, examples which are mentioned especially, are better defense of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses and an increased tolerance of the plants to certain herbicidal active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), corn, soybeans, potatoes, cotton, tobacco, oilseed rape and fruit plants (with the fruits apples, pears, citrus fruits and grapes), with particular emphasis on corn, soybeans, potatoes, cotton, tobacco, and oilseed rape. Traits which are especially emphasized are the increased defense of the plants against insects, arachnids, nematodes, and slugs and snails owing to toxins being formed in the plants, in particular toxins which are generated in the plants by the genetic material of Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c Cry2Ab, Cry3Bb and CryIF and their combinations; hereinbelow “Bt plants”). Other traits which are particularly emphasized are the increased defense of plants against fungi, bacteria and viruses by the systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Other traits which are especially emphasized are the increased tolerance of the plants to certain herbicidal active compounds, for example imidazolinones, sulfonylureas, glyphosate or phosphinotricin (for example “PAT” gene). The genes which confer the desired traits in each case may also be present in the transgenic plants in combination with one another. Examples of “Bt plants” which may be mentioned are corn cultivars, cotton cultivars, soybean cultivars and potato cultivars which are commercially available under the trade names YIELD GARD® (for example corn, cotton, soybean), KnockOut® (for example corn), StarLink® (for example corn), Bollgard® (cotton), Nucoton® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are corn cultivars, cotton cultivars and soybean cultivars which are commercially available under the trade names Roundup Ready® (tolerance to glyphosate, for example corn, cotton, soybean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulfonylureas, for example corn). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include also the varieties commercially available under the name Clearfield® (for example corn). Naturally, these statements also apply to plant cultivars having these genetic traits or genetic traits still to be developed, which plant cultivars will be developed and/or marketed in the future.

The plants listed can be treated particularly advantageously according to the invention with the compounds of the general formula (I) or the active compound mixtures according to the invention. The preferred ranges stated above for the active compounds and mixtures also apply to the treatment of these plants. Particular emphasis may be given to the treatment of plants with the compounds or mixtures specifically mentioned in the present text.

The preparation and the use of the active compounds according to the invention is illustrated in the examples below.

PREPARATION EXAMPLES Example 1

At room temperature, 273 mg (1.0 mmol) of 3-iodo-1-methyl-1H-pyrazole-4-carboxylic acid, 213 mg (0.83 mmol) of 3′,4′-dichloro-5-fluorobiphenyl-2-amine, 0.3 ml (1.67 mmol) of N,N-diisopropyl-ethylamine and 583 mg (1.25 mmol) of bromotripyrrolidinophosphonium hexafluorophosphate were stirred in 5 ml of methylene chloride for 3 days. The mixture was washed with saturated sodium bicarbonate solution and then with water. Removal and concentration of the organic phase gave 910 mg of crude product. Purification by column chromatography on silica gel 60 using methylene chloride/diethyl ether 5:1 gave 230 mg (53.5% of theory) of N-(3′,4′-dichloro-5-fluoro-1,1′-biphenyl-2-yl)-3-iodo-1-methyl-1H-pyrazole-4-carboxamide (compound No. 6 from table 1) of logP (pH 2.3)=3.42.

Preparation of the Starting Materials of the Formula (II) Example (II-1)

Step 1:

13 ml of isoamyl nitrite were initially charged in 80 ml of methylene iodide. At 100° C., 10.2 g (60.3 mmol) of ethyl 3-amino-1-methyl-1H-pyrazole-4-carboxylate (XIV-1) were added dropwise. After 15 min of stirring at this temperature, the mixture was concentrated.

This gave 15.2 g (79% of theory) of ethyl 3-iodo-1-methyl-1H-pyrazole-4-carboxylate [logP (pH 2.3)=1.74] which was used without further work-up.

Step 2:

134 g (0.478 mol) of ethyl 3-iodo-1-methyl-1H-pyrazole-4-carboxylate were initially charged in 850 ml of ethanol, and a solution of 29.5 g (0.526 mol) of KOH in 340 ml of water was added dropwise. After 2 days of stirring at room temperature, the mixture was concentrated, the residue was taken up in water and extracted with ethyl acetate and, after separation, the aqueous phase was adjusted to pH 1 using hydrochloric acid, resulting in the precipitation of a solid. Filtration with suction and 3 hours of drying under reduced pressure at 40° C. gave 88 g (70% of theory) of 3-iodo-1-methyl-1H-pyrazole-4-carboxylic acid [logP (pH 2.3)=0.57]. The aqueous phase was extracted with ethyl acetate and the organic phase was concentrated, which gave another 5.1 g (2.1% of theory) of product.

Preparation of the Starting Materials of the Formula (XIV) Example (XIV-1)

At room temperature, 100 ml of concentrated hydrochloric acid were added dropwise over a period of 20 min to a suspension of 220 g (0.855 mol) of ethyl 3-(N′-benzylidene-N-methylhydrazino)-2-cyanoacrylate (XVI-1) in 1000 ml of ethanol. The mixture was then heated at the boil for 1 hour. After removal of the solvent, the oily residue was triturated with gentle heating with 200 ml of diethyl ether, resulting in the precipitation of a solid. Filtration with suction gave 149 g (95% of theory) of ethyl 3-amino-1-methyl-1H-pyrazole-4-carboxylate [logP (pH 2.3)=0.72].

Preparation of the Starting Materials of the Formula (XVI) Example (XVI-1)

258 g (1.92 mol) of N-benzylidene-N′-methylhydrazine and 325 g (1.92 mol) of ethyl ethoxy-methylenecyanoacetate were initially charged in 1000 ml of toluene and heated at the boil for 1 hour. After cooling, the mixture was filtered off with suction, which gave 447 g (89.5% of theory) of ethyl 3-(N′-benzylidene-N-methylhydrazino)-2-cyanoacrylate [logP (pH 2.3)=2.31]. The filtrate was allowed to stand for 16 hours and then again filtered off with suction, which gave another 7.7 g (1.5% of theory) of the desired product.

The given logP values were determined in accordance with EEC directive 79/831 Annex V.A8 by HPLC (High Performance Liquid Chromatography) on a reversed-phase column (C 18). Temperature: 43° C.

Mobile phases for the determination in the acidic range (pH 2.3): 0.1% aqueous phosphoric acid, acetonitrile; linear gradient from 10% acetonitrile to 90% acetonitrile.

Calibration was carried out using unbranched alkan-2-ones (having 3 to 16 carbon atoms) with known logP values (determination of the logP values by the retention times using linear interpolation between two successive alkanones).

The lambda max values were determined in the maxima of the chromatographic signals using the UV spectra from 200 nm to 400 nm.
